The Turanor Planet Solar Catamaran is the largest solar powered sea vessel. The round the world trip it has undertaken has made it the symbol of energy efficiency and sustainable energy. Tûranor aims to break-records and raise awareness of energy efficiency. To draw attention to the matter it sailed into the harbor of Cancun, on the east coast of Mexico, which is playing host to the United Nations climate talks.

The energy efficient boat is 102 ft long, 29ft wide and 25ft high and has 500 solar high efficiency units that cover some 540 square feet. The large boat can accommodate up to 200 persons and move at a fairly good speed without adding to the pollution of any kind as it is completely silent. It can hit a top speed of 15 knots.

The boat was built by Knierim Yachtbau at Kiel, Germany. It cost a cool £10million to build and is in the process of achieving a series of record-breaking feats as it circumnavigates the globe, while also promoting the use of sustainable energy. It set off from Monaco for the trip on September 27 this year and the 31,000 mile journey is expected to conclude in spring 2012.

The MS Turanor PlanetSolar is going to achieve its world tour on May 4th, 2012 in Monaco.
